There’s an image going round the internet at the moment. Have you seen it? It’s a photograph from a freelance photographer of one of the refugees from Syria, a father, holding his children in his arms, another adult, maybe his wife, leaning in towards him with head bowed. Behind him are other refugees, blurred out of focus, and the great, grey sea. His face is etched with grief, horror, relief and a wild, grim desperation. This man is being held up as the true face of the refugees – a whole horde of humanity determinedly, desperately escaping untenable circumstances in their home country.
